Hi,
Try opening Secure/Login.aspx with a text editor and cut out this part:
<portal:OpenIDLoginControl id="oidLogin" runat="server"></portal:OpenIDLoginControl>
also make sue this is set to false in Web.config and user.config if using a user.config file:
<add key="EnableOpenIDAuthentication" value="false" />
and delete the janrain stuff from bin folder.
Hope it helps,
Joe
